This commit introduces `FullScreenContainedLoader` and replaces usages of `FullScreenLoader` where appropriate.
It also updates several composables to use `rememberUpdatedState` for lambda parameters to ensure the latest versions are used.
Additionally, the following changes are included:
- Add a setting to show/hide the attachment button in the chat input bar.
- Implement navigation to `PhotoViewScreen` when a photo attachment is clicked in a message.
- Add "Copy link" and "Copy image" actions to `PhotoViewScreen`.
- Remove unused settings and their corresponding logic from `SettingsViewModel` and `UserSettings`.
